The study takes multiple choice cloze test in 2015 before reform and bank cloze test after reform in 2016 as research subjects, and research data are from true test results of 48 test-takers. The performance analysis was done by using FACETS(Version 2.7) and SPSS 19.0. This research aims at exploring the relationships between two different cloze forms and the differentiated performance of test-takers, and also testing reliability and validity of two cloze forms. Results show that multiple choice cloze test and banked cloze test have great difference on reflecting test-takers' English ability. Banked cloze test can better reflect test-takers' English ability if more items are added.展开更多

The purpose of the study is to compare the changes of the blood glucose levels in transfused and non-transfused patients during LT. METHODS: A retrospective study on 60 biliary pediatric patients and 16 adult patients undergoing LT was carried out. Transfused pediatric patients were included in Group Ⅰ (GⅠ), those not transfused in Group Ⅱ (GⅡ). Twelve adult patients were not given transfusion and assigned to Group Ⅲ(GⅢ); whereas, four adult patients who received massive transfusion were assigned to Group Ⅳ (GⅣ). The blood glucose levels, volume of blood transfused, and the volume of crystalloid infused were recorded, compared and analyzed. RESULTS: Results showed that the changes in blood glucose levels during LT for both non-transfused and minimally transfused pediatric groups and non-transfused and massively-transfused adult groups were almost the same. CONCLUSION: We conclude that blood transfusion does not cause significant changes in the blood glucose levels in this study.展开更多

Employing simultaneous introspection and immediate retrospection, the study is conducted among 18 non-English major students. After examining their test-taking processes, a framework for analyzing testees' test-taking processes for banked cloze test is put forward. And then the researcher applies this framework to analyze the testees' protocols. Results show that regarding information sources, clause-level information accounts for the largest proportion, followed by text-level information, sentence-level information and extra-textual information, and in terms of strategies, the testees show a clear preference for bottom-up processing strategies, followed by top-down processing strategies and test-wise processing strategies. The verbal protocols have further revealed that the proficient readers seem to have a context-based reading model and they prefer to grasp the gist of the text, whereas the less proficient readers often employ word-based approaches and they are apt to identify parts of the text.展开更多

The aim of the present study is to improve the performance of a distribution network by successively applying mono-capacitor positioning, multiple positioning and reconfiguration processes using GA-based algorithms implemented in a Matlab environment. From the diagnostic study of this network, it was observed that a minimum voltage of 0.90 pu induces a voltage deviation of 5.26%, followed by active and reactive losses of 425.08 kW and 435.09 kVAR, respectively. Single placement with the NSGAII resulted in the placement of a 3000 kVAR capacitor at node 128, which proved to be the invariably neuralgic point. Multiple placements resulted in a 21.55% reduction in losses and a 0.74% regression in voltage profile performance. After topology optimization, the loss profile improved by 65.08% and the voltage profile improved by 1.05%. Genetic algorithms are efficient and effective tools for improving the performance of distribution networks, whose degradation is often dynamic due to the natural variability of loads.展开更多

文摘The present study investigates the testees' test-taking process for banked cloze, focusing on the following two aspects: the information sources and strategies. Employing simultaneous introspection and immediate retrospection, the study is conducted among 18 non-English major students. After examining their test-taking processes, a framework for analyzing testees' test-taking processes for banked cloze test is put forward. And then the researcher applies this framework to analyze the testees' protocols. Results show that regarding information sources, clause-level information accounts for the largest proportion, followed by text-level information, sentence-level information and extra-textual information, and in terms of strategies, the testees show a clear preference for bottom-up processing strategies, followed by top-down processing strategies and test-wise processing strategies. The verbal protocols have further revealed that the proficient readers seem to have a context-based reading model and they prefer to grasp the gist of the text, whereas the less proficient readers often employ word-based approaches and they are apt to identify parts of the text.

文摘In the paper,copepod universal formulas are applied to construct a copepod individual-based model(IBM),and a genetic algorithm(GA)is incorporated in the formulas with genes as species parameters.The IBM initially constructs the individuals with all possible genes similar to the original state of natural selection.Climate-averaged temperature and chlorophyll a(Chl a)time series at the surface layer of fixed points in the Georges Bank(GB)and the Gulf of Maine(GOM)are taken as the model environment.The IBM has been running for 50 a in the environment without inter-annual change.The IBM results indicate that some of the life history traits of the top ten abundant species output by the IBM in the GB and the GOM are consistent with the real species Calanus finmarchicus,Pseudocalanus spp.,Centropages typicus,and Centropages hamatus in terms of reproduction strategy,time to reach the maximum abundance,water temperature preference,and adult body mass.The study of the top ten abundant species with multidimensional scaling(MDS)and clustering analysis(CA)methods indicates that reproduction strategy is the basis for grouping.For the species taking the broadcasting strategy,both GB and GOM environments tend to choose smallbodied species with cold-water preference,such as Pseudocalanus spp.;for the species taking the egg-carrying strategies,the GB environment selects large-bodied species with cold-water preference,such as C.finmarchicus,while the GOM environment selects medium-bodied species with warm-water preference,such as Centropages spp.(C.typicus and C.hamatus).After gene mutation is added to the IBM,the model result gets simple,which needs to be further improved.The significance of the paper lies in systematically studying the impact of GB and GOM environments on the evolutionary life history traits of copepods for the first time.

文摘Rapid and reliable onboard optimization of bank angle profiles is crucial for mitigating uncertainties during Mars atmospheric entry.This paper presents a neural-network-accelerated methodology for optimizing parametric bank angle profiles in Mars atmospheric entry missions.The methodology includes a universal approach to handling path constraints and a reliable solution method based on the Particle Swarm Optimization(PSO)algorithm.For illustrative purposes,a mission with the objective of maximizing terminal altitude is considered.The original entry optimization problem is converted into optimizing three coefficients for the bank angle profiles with terminal constraints by formulating a parametric Mars entry bank angle profile and constraint handling methods.The parameter optimization problem is addressed using the PSO algorithm,with reliability enhanced by increasing the PSO swarm size.To improve computational efficiency,an enhanced Deep Operator Network(Deep ONet)is used as a dynamics solver to predict terminal states under various bank angle profiles rapidly.Numerical simulations demonstrate that the proposed methodology ensures reliable convergence with a sufficiently large PSO swarm while maintaining high computational efficiency facilitated by the neural-network-based dynamics solver.Compared to the existing methodologies,this methodology offers a streamlined process,the reduced sensitivity to initial guesses,and the improved computational efficiency.
文摘This research centers on commercial banks'human resource allocation.It constructs a staffing model grounded in human capital value creation theory and analyzes relevant factors through longitudinal panel data regression.Taking City Commercial Bank A as an instance,the model identifies 12.3%redundant positions and matches jobs with business scale.Additionally,the study proposes a“staffing effectiveness salary”system,providing a framework for optimizing commercial bank human capital in the digital age.
